Growing a garden or trees on your property requires a lot of patience and time.

You don’t necessarily have to have gardening skills to do it. However, you do need to have the right products and tools for the job.

If you want citrus fruits, it is important to find the best trees for your preferences.

You need to know how to plant everything correctly. However, you also need to choose the best fertilizer for citrus trees, as well.

What Kind of Fertilizer for Citrus Trees?

You will find a variety of citrus trees. These can include lemons, oranges, limes, and grapefruit. Some trees bloom and produce fruit at different times throughout the year. It is important to learn when these trees bloom and when to plant them for the best fruit selection.

Some trees can be grown inside your house or business, such as the kaffir lime tree. However, most citrus trees grow so large that they must be planted outdoors. You may be able to keep the tree inside while it is small, though.

Within the list of citrus trees, you can find many different species. For example, an orange tree can produce navel oranges, blood oranges, or mandarin oranges. It depends on the species that you choose.

The fertilizer you select matters because there are many fertilizers on the market. Make sure that the product shows that it can be used on citrus-producing trees because then you can use it on any citrus tree. The key is to choose the right fertilizer.

The first step is to make sure the product is designed for citrus trees. Once you find a variety of fertilizers that do that, you can choose the one you like best.

It might be best to use the spikes if you are busy and don’t want to walk around spraying each tree. The sprays might be best if you want longevity. Each product is different, so you need to pay close attention to each one’s ability.

Best Citrus Tree Fertilizer Reviews

1. Miracle-Gro 1048291 Citrus, Mango, Avocado Shake ‘n Feed Plant Food

The Miracle-Gro Citrus, Mango, Avocado Shake ‘n Feed Plant Food comes in a 4.5-pound container. It offers continuously released plant food. This means you can shake out the recommended amount once, and it feeds the plant for a long time.

This fertilizer comes in a 8-2-10 (nitrogen-phosphate-potash) formulation. Most of the time, fertilizer formulas all include these three numbers, and they always indicate the percentage of those nutrients. It is common for citrus tree fertilizers to have more nitrogen and potash/potassium than phosphate because those nutrients get depleted faster.

You can use this fertilizer on existing and new in-ground citrus trees, as well as mango and avocado trees. It contains more magnesium, potassium, iron, and sulfur. Citrus plants need more of these minerals to prevent nutrient deficiency.

One application of this product can feed your plant up to three months. The continuous release option ensures that you do not burn nor overfeed your plant.

It also makes it easier to feed your plant. You measure out the right amount of food and sprinkle it around the tree. You don’t have to mix anything or guess at the right amount of fertilizer.

2. JR Peters Inc 52524 Jacks Classic Citrus Food Fertilizer

The JR Peters Jack’s Classic Citrus Fertilizer comes in a one-pound bucket with a resealable lid. It comes in the 20-10-20 formulation. It’s designed to give the right combination of nutrients.

The advanced formulation gives your plant high-quality nutrients. You can deliver more professional-looking results to your garden at home.

Jack’s Citrus feed also helps your plants take in more nutrients. The plant can get nutrients through the leaves and roots.

With the product, you get a pre-measured scoop. Just use one scoop for each gallon of water when it is time to feed. Make sure you know how much water your tree needs to live and grow.

Citrus trees tend to need regular watering when they are new. This can take up to two years.

It’s most helpful to dig a small moat around the tree, usually eight inches from the trunk, and keep it moist. When you fertilize, know how many gallons of water you’ll need and mix up that much food, and then feed your plant.

3. Jobe’s Organics Fruit & Citrus Fertilizer Spikes

The Jobe’s Organics Fruit/Citrus Fertilizer Spikes are more efficient than sprays because they don’t require any mixing. If you want to have organic fruits, it is important to use organic fertilizer and soil. However, this product is designed for potted citrus trees.

You get six spikes in one package, but you can purchase three or four packages at once. This allows you to save a few dollars and get more spikes.

All of Jobe’s Organics products come with Biozome. It’s a combination of Archaea, Mycorrhizal fungi, and healthy bacteria. This proprietary blend improves the soil’s quality. It also increases root mass and helps your plants fight disease.

Please note that the instructions on the bag are for outside trees. You shouldn’t use the same directions for indoor plants because you will over-fertilize them. Instead of using one cup of the mixture, use 1/4-cup of the fertilizer for best results.

When to Fertilize Citrus Trees?

Citrus trees need the right nutrients to grow. They can require a lot of food, so it is important to fertilize them at the right time. That way, you have a healthy tree that bears plenty of fruit.

It is important to fertilize your citrus tree during its active growth period. This is during the summer and spring. It is best to fertilize every one or two months.

Most people also recommend that you fertilize the tree during its dormant period. This is during the winter and fall months, and you should fertilize every two to three months.

It is important to fertilize at the right time to ensure that your citrus tree grows and produces fruit. The winter and fall months should not be skipped. You want the tree to start producing fruit as soon as possible.

If you wait to fertilize until the spring and summer months, your plant is already behind. It is already hungry and trying to grow. Therefore, it might produce blossoms and fruit much later than anticipated.

You also need to know how old the citrus tree is. When the tree gets older, you don’t have to fertilize during the dormant season. You may also have to fertilize less often during the regular growing season.

You can also use your judgment. If your tree has dark green, lush leaves, you probably don’t need to fertilize. If it doesn’t look healthy or the leaves are yellowing, you should go ahead and fertilize.

How Often to Fertilize Citrus Trees?

Knowing when to fertilize your citrus tree is important. However, you also need to know how often to do it. For new trees, it is important to fertilize regularly.

The problem is that it is easy to over-fertilize your tree. If you do that, it could ‘burn’ the tree and kill it. Therefore, you should read the package directions on your fertilizer for best results.

When you fertilize and how often is also based on the type of fertilizer you buy. Some fertilizers are designed to last for many months. If your fertilizer is designed to last for three months, you should fertilize every three months like clockwork.

If you over-fertilize, your plant could die. It might get too many nutrients, which could kill it or cause it to go into overdrive.

It might seem like a good idea to over-fertilize. That way, you get more fruit and larger fruits. However, the opposite is usually true – you get less fruit, and it isn’t very big.

How to Fertilize Citrus Trees?

You can fertilize your citrus tree in many ways. You can do it through the roots or the leaves. Many products on the market are designed to do both.

It is important to follow the directions on your fertilizer package. You can find sprayed fertilizers, granules, and spikes.

You will need to know a few things about your tree. For example, you need to know the drip line.

The drip line is from the edge of the leaves to the ground. It is best to sprinkle/spray/insert your fertilizer around the drip line.

Sprays should be diluted. However, you can find sprays that are designed to be sprayed as is. Read the directions on your fertilizer to see how to dilute the liquid.

Granules do not need to be diluted or mixed with anything else. You will read the directions on the package to see how much you need. Usually, a scoop is included; you use however many scoops are necessary for the size of your tree.

Spikes work differently. Everything is pre-measured, so all you have to do is put the cap on the spike and drive it into the ground.

However, you need to establish the drip line first. Insert your spikes about two feet away from the center of the tree or near the drip line. Space the spikes about three feet apart for best results.

Conclusion

You now know that it is important to have good fertilizer for citrus trees. Without it, your tree could get diseased or have yellowed leaves. It might also suffer and not produce fruit as much as it should.

With fertilizer, your trees can look healthier, have greener leaves, and produce more fruit. You will be amazed at what a little work and fertilizer can do. However, it is important to choose the right product.

If you want something organic, you may want to go with Jobe’s products, as they are all organic. The spikes are easy to use and make fertilizing much easier. However, the Jobe’s Organics Fruit & Citrus Fertilizer Spikes are designed for indoor plants.

For larger trees (outside), you may want to consider the Espoma Citrus-tone Plant Food. It is suitable for all types (including indoor trees). It also has similar ingredients.

Citrus Care

Jerry Coleby-Williams

JERRY COLEBY-WILLIAMS: Citrus are wonderful fruit trees, but they’re very hungry. If you give them what they want, when they want it, then they’ll amply reward you for years, but if you don’t, they’ll quickly let you know that something’s wrong.

Now as a general purpose fertiliser, I like to use poultry manure. You won’t find a more complete fertiliser than this and I feed citrus every 6 weeks from spring, summer, through to autumn and I give them half a handful per square metre and you sprinkle this very thinly around the root zone.

Now if a tree is mulched, you put it underneath the mulch and then put the mulch back over it – just in case you get heavy rain, that stops any of the fertiliser from being washed away, but you don’t apply a poultry manure if they’re flowering – you wait until the fruit are this size. If you apply it while they’re flowering, they’ll drop their fruit.

Now citrus also need quite a lot of iron and they like a slightly acidic soil, so what I do is I use iron sulphate and I put one tablespoon in 4 and half litres of water and I apply that to each citrus – once in spring, once in summer and once in autumn.

Another thing that citrus need – particularly in Australian soils – is trace elements or micro-nutrients. These contain funny little things like boron, magnesium and molybdenum. Now these things are wonderful if you add a small amount, but if you add too much, it can be lethal – so just one pinch in 4 and half litres of water, per tree, per year.

And to make sure that the soil is well nourished, I love to use seaweed. Seaweed contains things like selenium and iodine * , plus it contains folic acid and that’s wonderful for your fungi and bacteria in the soil. It brings the soil in to life. Now that’s about 3 tablespoons in 4 and a half litres of water…and I’m going to give that a little bit of a mix and a bit of a stir before I apply it. There we go.

This sort of a fillip is something that I give to my citrus in spring. That’s a good time to start citrus into growth and you just water this in generously around the root zone.

Lastly, it’s important to prevent citrus from fruiting for the first 3 years. Now I know this hurts, but you’ve got to pinch off the fruit. This directs the energy into producing branches which are strong enough to support the abundant crops that will result from correct and consistent feeding.

Keep reading for tips on fertilizing lemons.

Lemon Tree Fertilizer

Most of the time, people know the basics of how to grow a lemon tree, but they are uncertain about lemon tree fertilizer. Fertilizer for a lemon tree should be high in nitrogen and should not have any number in the formula higher than 8 (8-8-8).

When to Apply Fertilizer for Lemon Trees

When growing a lemon tree, you want to make sure that you apply fertilizer at the proper times. Lemon trees should be fertilized no more than four times a year and should not be fertilized in the coolest season when it is not in active growth.

How to Apply Lemon Tree Fertilizer

Knowing how to grow a lemon tree that produces fruit means you need to know how to apply fertilizer for a lemon tree. You want to apply the fertilizer in a circle around the tree that is as wide as the tree is tall. Many people make the mistake of placing fertilizer just at the base of growing lemon trees, which means that the fertilizer does not get to the root system.

If your lemon tree is 3 feet tall, apply fertilizer for the lemon tree in a 3-foot circle around the tree. If your lemon tree is 20 feet tall, fertilizing lemons would include an application in a 20-foot circle around the tree. This ensures that the fertilizer will reach the entire root system of the tree.

Growing lemon trees in the garden can be rewarding. Understanding how to grow a lemon tree and how to fertilize it properly will help make sure that you will be rewarded with lovely yellow lemons.

Why choose the best fertilizer for lemon trees?

What is the best fertilizer for lemon trees?

Here is a quick preview of our top 5 options on the market

  • BGI Fertilizers CitrusGain
  • Jobe’s Organics Fruit & Citrus Fertilizer with Biozome
  • Espoma Citrus-tone 5-2-6 Plant Food
  • Dr. Earth Blood Meal
  • Down to Earth Fish Meal Fertilizer

Before we talk about why we think these are the best, first let’s talk about what to look for in a citrus fertilizer.

What to look for in a good fertilizer for lemon trees

Fertilizing lemon trees follows the typical protocol growers use to keep citrus trees healthy and strong.

Citrus trees are heavy feeders; it is best to fertilize them every 4-6 weeks during their active growing season (spring and summer) and every 1-3 months during the dormant period (fall and winter).

Lemon trees need a fertilizer containing a good quality source of nitrogen.

The nutrient ratio of fertilizers used to feed lemon trees should be no higher than 8-8-8 for optimum growth. These numbers found on a fertilizer label are the N-P-K ratio; the consumer can look at this ratio and determine the percentage, by weight, of the nitrogen (N), phosphorus (P) and potassium (K) in the fertilizer.

For example, in an 8-8-8 formula, a 10-pound bag of fertilizer would contain the following: 0.8 pounds of nitrogen, 0.8 pounds of phosphorus and 0.8 pounds of potassium.

All plants have essential nutrients needed for growth. Nitrogen is one of the main essential nutrients; its main responsibility in a plant is vegetative growth.

It is used in the plant to construct amino acids which are the building blocks for protein; nitrogen is a major component of chlorophyll and helps to make the foliage green, and it is also necessary for the plant’s enzymatic reactions.

Phosphorus is a component in DNA and RNA (the genetic building blocks within plant cells) and is needed for root growth and flowering.

Potassium works more indirectly than the other two nutrients. It is not a component of any plant parts but activates many of the enzymatic reactions that occur within the plant, making it imperative for overall plant health.

Are Coffee Grounds Good For Lemon Trees?

Yes, coffee grounds are good for lemon trees. Lemon trees love soil that is acidic. Applying a coffee ground mulch or pine needles around your tree can help to acidify soil that has a low pH level.

Keep in mind the target pH level is 6.5 for lemon trees. Always test your soil so that you are not adding too much acid.

When Should I Fertilize My Potted Lemon Tree?

You should fertilize your potted lemon tree once a year if you are using granular plant food. If you are using a liquid option you need to follow the recommended doses on the package, it most cases it is once every 2 weeks.

If possible, I recommend using a granular plant food as it slowly allows the nutrients to be released into the soil without overfeeding your plant.

Are eggshells good for lemon trees?

Yes, eggshells are great for lemon trees. Placing crushed eggshells around your tree is a great way to give them natural organic nutrients that they need to thrive. Once such ingredient is calcium.

Eggshells are high in calcium and are easy to slowly feed it to your plants.

Growing Organic Citrus

Every home should have at least one citrus tree in the garden, where suited to the climate, to provide delicious fruits packed with vitamin C. Few things beat a freshly picked juicy tangerine just off the tree, or squeezing a little fresh lemon juice on your organic salad. Citrus trees have shiny evergreen leaves, fragrant flowers, and attractive fruits that hang for months without dropping. In northern climates, you can grow dwarf citrus trees in containers and bring them indoors during the winter.

Selecting Trees
There are so many types of citrus that you may have trouble deciding which to grow. Edible types include grapefruit, lemon, lime, kumquat, mandarin orange, tangerine, orange, tangelo, and temple orange.

Consider the yearly range of temperatures and possible frost, when making your selection. Local nurseries usually stock citrus that grow well in the area. The fruit of all types is easily damaged by frost, but the leaves and wood of some are more cold-resistant. In general, limes are the least hardy, oranges slightly hardier; kumquats are the most hardy, withstanding low winter frost temperatures.

A single mature citrus tree yields more than enough fruit for a family. If you plant more than one tree of the same type, select cultivars with different harvest times, or plant different types of citrus so you won’t be overwhelmed with one kind of fruit. Almost all citrus are self-pollinating. A few hybrids are not; be sure to check for the kind you want when you buy.

Select sturdy nursery-raised trees. A one-year-old tree should have a trunk diameter of ¾ inch. A two-year-old plant should have a diameter of at least 1 inch. Those with fewer fruits and flowers are better because they have put more energy into sturdy top and root growth.

Rootstocks
Most commercially grown citrus fruits are grafted onto rootstocks that are resistant to frost and insect attack. Select the proper citrus for your area when your soil is susceptible to nematode attack and other soil problems. Your local extension office or a good quality nursery could tell you what rootstock is best in your region.

Planting
Citrus do best at pH 6.0-6.5. They are not fussy about soil but do require good drainage. If drainage is a problem, plant trees in a raised soil mound, about 1½ feet high.

Select a sheltered area with full sun, such as a sheltered, south-facing alcove of a building. Citrus flowers attract bees, so don’t plant them in high-traffic areas.

It is best to plant citrus in late winter or early spring. Keep the graft union six inches above soil surface when planting. Full-sized trees require at least 25 feet between trees; smaller trees need less.

Citrus bark is thin and easily sunburned. Wrap the trunk with commercial tree wrap or newspaper for the first year, or paint it with diluted white latex paint.

Care
In dry areas, water newly planted trees at least once a week for the first year. Once established, trees need less-frequent watering, but never wait until leaves wilt to water. Water stress can cause developing fruit to drop; prolonged drought causes leaf drop and may kill the tree. Water slowly and deeply; shallow sprinkling does more harm than good. In drought areas, construct a shallow watering basin that extends from six inches away from the trunk to one foot beyond the drip line. Or install drip irrigation under a thick layer of mulch to conserve water and protect shallow feeder roots. Keep mulch six inches away from the trunk.

In citrus-growing areas, soils often lack organic matter and nitrogen. Spread compost, mulch and Dr. Earth® Fruit Tree Fertilizer on the soil surface out to the drip line four times a year, beginning in February. This will help to ensure a healthy productive crop that will be full of nutrition for you and your family.

Pruning
Most citrus trees need little pruning beyond removing dead or broken branches. Limit the tree’s size by thinning out fast growing shoots that outgrow other branches. Thin the branches, rather than shortening them. Remove suckers as soon as they emerge from the ground.

You can revitalize an old unproductive citrus tree by pruning severely in early spring. Wear thick gloves if the tree has thorns. Cut off all branches two inches or larger in diameter flush to the trunk, and feed and water heavily for the next year. Note: Very severe pruning may stop fruiting for up to two years.

Winter Protection
Citrus are usually grown outdoors in climates where frost is rare. Some types of citrus fruit are vulnerable when frost does occur. In areas where mild frost is common, don’t plant cultivars that bear in winter and early spring. Since succulent new growth is more prone to frost injury, withhold extra water in late summer to limit new growth. When frost does threaten, cover trees with large fabric sheets. Use fans to keep air circulating around the trees. If symptoms of frost damage appear, wait until spring growth starts to see the true extent of damage. A tree that loses all its leaves can still rejuvenate. If damage is severe, dieback may continue during the growing season.

Harvesting
Citrus trees usually bear in three to four years. It can be hard to tell when citrus fruit is ready to pick. Color is not a good indicator. Fruit can have ripe coloration several months before being ready to harvest or remain green and unappealing even when ripe and juicy inside. Use the taste test to determine when fruit is at its peak flavor. Allow fruit to ripen on the tree before picking.

Use pruning shears to cut stems close to the fruit when harvesting. Don’t just pull fruit off the tree. Ripe citrus fruit can remain on the tree for up to three months. Once harvested, citrus can be stored in the refrigerator for three more weeks. Enjoy the fruits of your labor; they will be juicy and full of flavor and nutrition.

Citrus trees produce the most fruit when fed properly.

Many people in warm climates grow fruit trees either in the landscape or in containers, but are often uncertain of how to care for them. Citrus trees are heavy feeders, and in order to have flowers and fruit, they need to be fertilized regularly. The amount of fertilizer you will use depends on the size and age of your trees.

The most common mistakes home gardeners make are not fertilizing their citrus trees enough, not fertilizing regularly, or not using proper amounts of fertilizer. Most fruiting trees should be fertilized in early spring before the trees are in bloom. If you miss your early feeding, don’t fertilize until the fruit is about the size of a pea, usually around mid-May.

Young Citrus Trees:

In Florida and humid climates, begin fertilizing new trees at the beginning of the growing season in February, just as the buds begin to swell.

Year one, apply about 1/2 pound of citrus-specific fertilizer, or a 10-10-10 fertilizer per tree, and reapply every 6 weeks through October.

In the second year, begin feeding at the start of the growing season 1 pound of fertilizer per tree, every 7 weeks through October.

In the third year, begin feeding at the start of the growing season 2 pounds of fertilizer per tree, every 9 weeks through October.

Mature Trees:

After they have been in the ground for three years, fertilize only 3 times a year in February, May and October. Feed at a rate of 1 pound of fertilizer for each year of the tree’s age. For instance, a citrus tree that is 7 years old would get 7 pounds of 10-10-10 fertilizer in 3 separate applications for a total of 21 pounds per year.

How to Apply Fertilizer to the Landscape:

  1. Spread fertilizer evenly over the ground in a band along the edge of the tree’s leaf canopy. Don’t spread it near the trunk.
  2. Water trees thoroughly after each application of fertilizer. This is especially critical in dry climates.

Feeding Citrus Trees in Containers:

Begin fertilizing potted citrus trees in early spring and stop in midsummer to allow your tree to prepare for winter. You can either use a slow-release fertilizer once a year in early spring or a liquid fertilizer every other week.

Look for a fertilizer labeled specifically for citrus, but if it isn’t available, use a fertilizer with twice as much nitrogen as phosphorous, such as 12-6-6.
